Special feed for Huai sows, capable of increasing farrowing rate of sows, and preparation method of special feed

Abstract

The invention discloses a preparation method of a special feed for Huai sows, capable of increasing the farrowing rate of sows. Based on a fermented soybean meal feed, a compound bacterium agent is used for fermenting a Chinese herbal medicine complete feed, part of feed protein is decomposed into small peptides and free amino acids, and sour fragrance is provided for a fermented feed, so that the palatability is improved, the feeding is promoted, the digestibility and the digestive ability of the feed are improved, and the growing performance of the sows is improved. The special feed has the effects in the respects of advanced sexual maturity, flushing, rapid postnatal oestrus and the like, the propagation rate is increased, and Chinese herbal medicines have the advantages of being low in toxicity, free from drug resistance, economical, practical, multifunctional and the like. The conversion rate, the bacteria resistance and the worm expelling capacity of the feed are notably increased, the production performance of the sows is improved, and the tolerance of the sows is improved. According to the feed for the sows, provided by the invention, the nutrient level of the sows can be effectively increased, the intestinal flora balance can be improved and maintained, the immunity and the disease resistance can be improved, the feed is free from antibiotics, green and safe, the farrowing rate of the Huai sows can be notably increased, and the breeding gain can be increased.

Description

technical field [0001] The invention relates to the technical field of pig feed, in particular to a preparation method and a preparation method of special feed for Huai pigs which can improve the birth rate of sows. Background technique [0002] As the modern pig farming industry has formed large-scale farming, the key to the economic benefits of farming is the reproductive capacity of sows. Now the reproductive capacity of sows in various farms generally shows that the sows have low estrus rate, small litter size, and low breeding efficiency. , seriously restricting the development of the pig industry. Factors affecting puberty of pigs of the same breed and age include feed level, intake of energy, protein, fat, vitamins and minerals, etc. If the nutritional level is too low or too high, the puberty age of piglets will be delayed. This will inevitably lead to prolonged average farrowing interval of adult sows, small litter size, and reduced reproductive rate. Therefore, on...
